H. H RsH COVER Filed Feb. 4, 1926 INVENTOR ATTORNEY I Patented June 10,1930 HARRY. HERSH, OF MILWAUKEE, WISCONSIN- COVER Application filedFebruary 4, 1926. Serial No. 85,871.

' end elevation, looking in the direction of the arrow marked 4' on Fig.1; Fig. is an end elevation, looking in the direction of the arrowmarked 5 on Fig. 1; Fig. 6 is a section of the cover taken on the line66 on Fig. 1, looking in the direction indicated by the arrows, the basebeing shown in elevation; Fig. 7 is a section of'the cover taken on theline 77 on Fig. 1, looking in the direction indicated by the arrows, thebase being shown in elevation; and Fig. 8 is an enlarged section ofdetails of construction.

Referring to the drawings, the reference numeral 1 designates a coverwhich is intended to be detachably secured to a base 2. The base 2 isintended to support any kind of adevice, not shown,which is secured tothe base 2, and the base2 is intended to be secured to any suitablesupport such as a wall of a room, for example.

The object of the invention is to provide a cover which can be readilyconnected with a base, or disconnected therefrom, without requiring theuse of-any tool, which will be cheap to construct, and which will befirmly held connected'with the base while readily removable from thebase and readily reen gageable with the base. i

Fig. 1 of the drawings'illustrates the cover and base in aperpenc'licular position as though the base were secured to the wall ofa room and the top parts of the base and cover are rounded, asdesignated by reference numorals 3 and 4, not only to give a pleasingappearance to the eye of an observer but also for an important principleof operation to be hereinafter described.

The bottom of the base 2 is preferably provided with a plurality ofnotches, or apertures, 5 and 6, while the top of'the base 2 ispreferably provided with only a single notch, or aperture, 7 Thisconstruction results in at least a three-point connection between thebitse and the cover and at opposite ends there 0 i In the specificconstruction illustrated'by the drawings, the base 2 is illustrated asprovided with an overturned edge 8 extending clear around the base, theedge 8 and the top 9'of the base'2 being connected by a curved part 10.It will be readily understood that the base 2'and the'cover 1 can beproduced cheaply by dies.

Lips 11,12, and 13 are struck inwardly on the cover 1 to enter thenotches 5, 6, and 7 to secure the cover 1 upon the base 2. Thenotches'5, '6, and 7 are preferably spaced from the back side 14 0f thebase 2 a'sufficient distance to leave catches 15, behind which the lips11, 12, and 13 may engage, and the lips 11, 12, and 13 are preferablyinclined, as clearly shown by Fig. 3 of the drawings, to hook behind thecatches 15 to'hold thezcover -1 securely connected with the base 2.

' in engaging it with the base 2 or disengaging 3 it from the base 2 isthat the cover isso shaped that pressure applied to the sides thereofwill elong'ate'the cover 2 so thata lip or lips will be disengaged froma'fnotch' or notches. If the fingers and thumb of a hand. apply pressureto the sides of the cover in the vicinity of the points Aand B on Fig. 1of the drawings'and the bottom of the cover 1s heldin contact with thebottom of the base, i

an elongation of the cover will be produced, as indicated by the dottedlines on Figs. 1 and 2 of the drawings, sufficient to disengage the lip11 from the notch 7 and the cover can be readily removed from the baseby swinging its top away from the base and then moving it downwardly.

In order to provide for a nice tight fit of the cover and to prevent itsbeing moved and to avoid any rattling noises, the cover is provided witha skirt 16 which projects beyond both sides 17 of the cover atapproximately its mid-length and also extends continuously around thebottom of the cover.

The skirt 16 can be omitted, if desired, as the principle ofconstruction and operation of ,the cover only requires that the sides 17of the cover avoid obstructions which would prevent their being pressedtowards each other. The skirt 16 also assists in keeping dirt fromentering between the cover .and the base. Fig. 6 of the drawingillustrates a practically dust and dirt proof fit between the cover andthe base and Fig. 7 of the drawings illustrates a practically dirt anddust proof fit between the sides 17 of the cover and the base. The coveris made of material, prefer- .ably metal, thin enough so that the sidescan be readily pressed towards each other by the thumb and finger of'ahand, and the curved parts 10 of the base permit the sides of the coverbeing pressed together, by rising slightly, so that the construction ispractically and substantially dust and dirt proof.

The invention is capable of being embodied in somewhat difierentconstructions from those illustrated by the drawings without departingfrom the principle of construction and operation of the invention whichis to have a flexible cover of such shape that com pression of the sidesof the cover produces an elongation of the cover at substantially rightangles to the direction of application of the pressure.

Thenotches 5, 6, and 7 may be of any suitable shape adapted to receivethe lips 11, 12, and 13. The drawings illustrate the lips 11, 12, and 13as punched inwardly at the edge 17 of the cover and at the edge of theskirt 1'6, and these lips may have their extremities 18 bent over tosecurely engage behind the catches 15, as clearly shown by Fig. 8 of thedrawings, for additional security.

lVhat I claim is 1. The combination with a base of substantiallyrectangular form having one end rounded, of a cup-shaped cover offlexible sheet material conforming substantially in shape and dimensionsto the base, and fitted thereover with its ends and sides in contactwith the base, portions of the sides of the cover adjacent the roundedend thereof being of p less width than the portions of the sidesadjacent the opposite end of the base, whereby by lateral pressure onsaid narrower portions of its side walls the cover may be elongated toseparate the rounded end thereof from the corresponding end of the base,for the purpose described.

2. The combination with a base of substantially rectangular form havingone end rounded, and having its side and end faces connected with itstop face by a curved surface, of a cup-shaped cover of flexible materialhaving substantially the outline of the base, and applied thereto,coacting latching means at the rounded ends of the cover and base forretaining the cover in position on the base, portions of the side wallsof the cover adjacent the rounded end thereof terminating substantiallyat the said curved surface of the base, and portions of said wallsadjacent the other end of the cover extending beyond said curved surfaceover the side faces of the base, whereby when pressure is exertedlaterally on said narrower portions of the sides of the cover the latterwill be elongated to disengage said latching means.

3. The combination with a base of substantially rectangular form havingone end rounded and provided with a notch or aperture, of a cup-shapedcover of flexible material having a marginal side wall surrounding thebase, the portion of the side wall of the cover conforming to therounded end of the base having a lip extending into said notch oraperture when the cover is applied to the base, the cover being adaptedto be elongated sufficient-ly to withdraw said lip from engagement withthe base by pressure exerted on the opposite sides of the cover atpoints adjacent the rounded end.

4. The combination with a cover, of a base extending partly within thecover, the cover and base having interengaging means for retaining thecover on the base, and the base having roundedsurfaces adjacent andwithin portions of the margin of the cover, whereby squeezing actionupon the cover margin will cause said margin to act as a wedge with saidrounded surfaces to free the cover from the base.

5. The combination with a base having a rounded surface connecting itstop and marginal faces, of a cover fitted to the base and including amarginal wall within which the base is positioned when the cover isapplied thereto, coacting latching means being provided on the cover andbase for retaining the cover in position and substantially oppositeportions of the free edge of the marginal wall of the cover being sorelated to the rounded surfaces of the base that by lateral pressure onsaid portions of said wall, said edge and surface will coact todisengage the latching means and free the cover from the base.

In witness whereof 1 hereto afiix my signature.
